GEBIET DER OFFENBARUNGAREA OF REVELATION
Diese Offenbarung bezieht sich auf Getriebe für Arbeitsfahrzeuge und insbesondere auf stufenlose Getriebe.This disclosure relates to transmissions for work vehicles, and more particularly to continuously variable transmissions.
HINTERGRUND DER OFFENBARUNGBACKGROUND OF THE REVELATION
In einer Vielzahl von Einstellungen kann es nützlich sein, sowohl einen herkömmlichen Motor (z. B. einen Verbrennungsmotor) als auch eine stufenlose Energiequelle (z. B. einen elektrischen oder hydrostatischen Motor, einen variablen Kettenantrieb usw.) zu verwenden, um nützliche Leistung bereitzustellen. Zum Beispiel kann ein Teil der Motorleistung umgeleitet werden, um eine erste stufenlose Maschine (z. B. eine als Generator wirkende erste elektrische Maschine) anzutreiben, die wiederum eine zweite stufenlose Maschine antreiben kann (z. B. eine zweite elektrische Maschine, die als ein Motor wirkt, der elektrischen Strom von der ersten elektrischen Maschine verwendet). In bestimmten Konfigurationen kann Leistung von beiden Arten von Quellen (d. h. ein Motor und eine stufenlose Energiequelle) für die endgültige Leistungsabgabe (z. B. an eine Fahrzeugachse) über ein schaltstufenloses oder stufenloses Getriebe („IVT“) kombiniert werden. Dies kann als „Split-Modus“- oder „Split-Path-Modus“-Operation bezeichnet werden, da die Energieübertragung zwischen dem mechanischen Weg vom Motor und dem stufenlosen Weg aufgeteilt werden kann.In a variety of settings, it may be useful to use both a conventional engine (eg, an internal combustion engine) and a continuously variable power source (eg, an electric or hydrostatic motor, a variable chain drive, etc.) for useful performance provide. For example, a portion of the engine power may be diverted to drive a first continuously variable engine (eg, a first electric machine acting as a generator), which in turn may drive a second continuously variable engine (eg, a second electric machine referred to as a) a motor is used which uses electric power from the first electric machine). In certain configurations, power from either type of source (i.e., a motor and a stepless power source) may be combined for the final power output (eg, to a vehicle axle) via a no-gear or continuously variable transmission ("IVT"). This can be referred to as a "split-mode" or "split-path-mode" operation because the energy transfer between the mechanical path can be split between the motor and the stepless path.
Der Split-Modus-Betrieb kann auf verschiedene bekannte Arten erreicht werden. Zum Beispiel kann ein Planetengetriebe verwendet werden, um Drehkraft von einem Motor und von einer elektrischen Maschine zu addieren, wobei die addierte Leistung nachgelagert innerhalb eines zugeordneten Antriebsstrangs übertragen wird. Dies kann die Lieferung von Energie (z. B. an Fahrzeugräder) mit einem stufenlosen effektiven Übersetzungsverhältnis ermöglichen.Split mode operation can be accomplished in several known ways. For example, a planetary gear may be used to add torque from an engine and from an electric machine, with the added power being transmitted downstream within an associated powertrain. This may allow the supply of energy (eg, to vehicle wheels) with a continuously variable transmission ratio.
Es können jedoch verschiedene Probleme auftreten, einschließlich Einschränkungen hinsichtlich der maximalen praktischen Geschwindigkeit der variablen Energiequellen, Kraftstoffeffizienz usw. Außerdem können diese IVTs relativ komplex sein. Sie können eine große Anzahl von Teilen enthalten. Daher kann die Herstellung und Montage des IVT sehr lange dauern. Darüber hinaus kann der IVT sehr sperrig sein und einen beträchtlichen Platz innerhalb des Fahrzeugs einnehmen. Ebenso kann der IVT erheblich zum Gesamtgewicht des Fahrzeugs beitragen, was sich negativ auf die Kraftstoffeffizienz auswirken kann.However, there may be several problems including limitations on the maximum practical speed of variable energy sources, fuel efficiency, etc. In addition, these IVTs may be relatively complex. They can contain a large number of parts. Therefore, the manufacture and assembly of the IVT can take a long time. In addition, the IVT can be very bulky and occupy considerable space within the vehicle. Likewise, the IVT can add significantly to the overall weight of the vehicle, which can negatively impact fuel efficiency.

In some embodiments, the engine may include an internal combustion engine (eg, a diesel engine), and the IVP source may include an electric or hydraulic engine.
Außerdem kann ein Variator enthalten sein, der Leistung von mehreren Energiequellen addiert. Zum Beispiel kann ein Planetengetriebe enthalten sein mit einer ersten Komponente, die Leistung von der Maschine erhält, einer zweiten Komponente, die Leistung von der IVP-Quelle empfängt, und einer dritten Komponente, die Leistung von der Maschine und der IVP-Quelle addiert und die addierte Leistung zu einem anderen Gerät ausgibt, das mit der dritten Komponente verbunden ist. Es versteht sich, dass eine solche Konfiguration im Wesentlichen stufenlose und kontinuierliche Übersetzungsverhältnisse für das Planetengetriebe ermöglichen kann. Zum Beispiel kann für eine feste Motordrehzahl ein bestimmtes Übersetzungsverhältnis durch Variieren der Geschwindigkeit des IVP in Bezug auf die Motordrehzahl eingestellt werden.In addition, a variator may be included that adds power from multiple energy sources. For example, a planetary gear may be included with a first component receiving power from the engine, a second component receiving power from the IVP source, and a third component adding power from the engine and the IVP source, and the third component outputs added power to another device connected to the third component. It will be understood that such a configuration may allow for substantially stepless and continuous gear ratios for the planetary gear. For example, for a fixed engine speed, a particular gear ratio may be adjusted by varying the speed of the IVP with respect to engine speed.
Der offenbarte IVT kann ferner eine Power Reverser-Vorrichtung umfassen. In einem ersten Modus (z. B. Vorwärtsmodus) kann die Power Reverser-Vorrichtung Leistung von einer der Leistungsquellen übertragen und eine Komponente des Variators in einer ersten Richtung (z. B. einer Vorwärtsrichtung) drehen. In einem zweiten Modus (z. B. Rückwärtsmodus) kann die Power Reverser-Vorrichtung Leistung von der Leistungsquelle übertragen und die Komponente des Variators in eine zweite Richtung (z. B. eine Rückwärtsrichtung) drehen. Dementsprechend kann der IVT in einigen Ausführungsformen stufenlose und kontinuierliche Übersetzungsverhältnisse in beiden Modi des Power Reversers bereitstellen. Wie noch erläutert wird, kann der Power Reverser relativ kompakt sein. Der Power Reverser kann eine relativ geringe Teilezahl haben. Außerdem kann das Gewicht des Power Reversers ziemlich gering sein. Zusätzlich kann ein Wechseln zwischen den verschiedenen Modi auf eine ziemlich sanfte und effiziente Weise erreicht werden.The disclosed IVT may further include a power reverser device. In a first mode (eg, forward mode), the power reverser device may transmit power from one of the power sources and rotate a component of the variator in a first direction (eg, a forward direction). In a second mode (eg, reverse mode), the power reverser device may transmit power from the power source and rotate the component of the variator in a second direction (eg, a reverse direction). Accordingly, in some embodiments, the IVT may provide stepless and continuous gear ratios in both modes of the power reverser. As will be explained, the power reverser can be relatively compact. The power reverser can have a relatively small number of parts. In addition, the weight of the power reverser can be quite low. In addition, switching between the various modes can be accomplished in a fairly gentle and efficient manner.
Darüber hinaus kann die Power Reverser-Vorrichtung in einigen Ausführungsformen die Einspeisung von der Energiequelle beschleunigen. Diese Beschleunigung kann es ermöglichen, dass die Einspeisung mehr einer anderen Einspeisung des Variators entspricht. Zusätzlich kann die Power Reverser-Vorrichtung ermöglichen, dass die addierte Ausgabe von Vorwärts zu Rückwärts umgeschaltet wird und dann in ein Getriebe (d. h. ein nachgelagertes Getriebe) ohne separate Rückwärtsgangelemente eingespeist wird. Ferner kann ein gleiches Drehmoment sowohl im Vorwärtsmodus als auch im Rückwärtsmodus bereitgestellt werden.In addition, in some embodiments, the power reverser device may accelerate the feed from the power source. This acceleration may allow the feed to be more similar to another feed of the variator. In addition, the power reverser device may allow the added output to be switched from forward to reverse and then fed into a transmission (ie, a downstream transmission) without separate reverse elements. Furthermore, an equal Torque be provided in both the forward mode and in the reverse mode.
